Electro Q

Tcos@ = mg
Tsin@ = σQ/2ε

so dividing, tan@ = σQ2εmg

i.e. σ is directly prop. to tan@

Thanks Ashish..., but wen we apply 2nd equation, then dont we get proportionality with sin theta????

Thats the mistake I made...Plz clarify that...Thanks

Plz clarify my doubt

brother T is itself a variable u have to eliminate it.
